Guess it depends on intended use. I have a Band-It tool in my damage control bag. Extremely useful for any number of "rough" attachment situations. May be habit - every damage control roll in the USN has a Band-It tool. The primary disadvantage I see with the ClampTite is your item B, above. Band-It uses approx 1/2" wide bands vice wire.

I have one.....It's not very easy or convenient to use, and needs lots of swing room which you may or may not have. I think you're better off using quality (removable) clamps for the purpose (Not cheap Home depot clamps). Quality stuff for a variety of hose materials are readily available at McMaster-Carr

We had a discussion of useful tools a couple of years ago and this one caught my eye as practical for a field repair, so I bought it. I then practiced with it a few times to get the hang of it. I keep a good supply of SS wire onboard, stored right between my duct tape and my WD40 and right behind my Rescue Tape.

Have had one for almost 20 years. It is an emergency tool that works very well. If you only put one loop of wire and tighten it down you are using it wrong and will likely cut your hose. Use three loops and it will probably hold forever. I keep mine and have used it several times, at home and on the boat, but ALWAYS replace asap with SS clamps. Why tempt fate?
